Description

Technical Field

[0001] This utility model belongs to the field of hydraulic pump station technology, and in particular relates to a hydraulic pump station control device with precise flow regulation function. Background Technology

[0002] After hydraulic pump stations achieve precise flow regulation, they can bring significant technical and economic advantages to industrial systems. Precise flow control ensures stable speed and force output of actuators, avoiding processing errors caused by flow fluctuations. It allows the pump's output flow to match the load demand in real time, reducing wasted energy and achieving energy savings of 20% to 40%. Long-term operation significantly reduces electricity costs. Precise flow control reduces hydraulic shock and pressure pulsation, lowers pipeline vibration and component wear, and extends the service life of pumps, valves, and seals. At the same time, stable flow reduces oil temperature fluctuations, preventing oil deterioration due to overheating and reducing maintenance frequency. Combined with proportional valves, servo valves, or electronic controllers, flow regulation can achieve digital programming and closed-loop feedback, quickly responding to changes in external commands. This is particularly important in automated production lines and robotic hydraulic drives, enabling complex functions such as multi-axis synchronization and dynamic speed regulation.

[0031] The working principle of the hydraulic pump station control equipment with precise flow regulation function provided by this utility model is as follows:

[0032] First step: During use, the motor 2 drives the hydraulic pump 3 to operate, drawing and transporting hydraulic oil from the oil storage tank, filling the pipelines within the equipment, including the relay oil cylinder 23, with oil. The direction of hydraulic oil delivery is controlled by the solenoid directional valve 8, thus supplying external hydraulic equipment. When the used hydraulic oil returns to the oil storage tank through the return oil pipe 9, it first enters the mounting cylinder 10, then flows into the filter cylinder 11 through the inlet impeller 12. After being filtered by the filter walls on both sides of the filter cylinder 11, it seeps out. The inner wall of the mounting cylinder 10 has seepage grooves, and the filtered hydraulic oil flows back to the oil storage tank along the seepage grooves for the next use. When the hydraulic pump 3 delivers oil, the electrically controlled valve 22 opens accordingly, and external air is replenished into the oil storage tank after processing to maintain pressure balance. The oil delivered by the hydraulic pump 3 first enters the relay oil cylinder 23. The level sensor 25 detects the oil level in the relay oil cylinder 23. If the oil level in the relay oil cylinder 23 is lower than the set value, a signal is sent to the control system, which controls the oil pump 3 to increase the oil delivery rate to maintain sufficient oil in the relay oil cylinder 23. The oil outlet pipe is located at the bottom of the relay oil cylinder 23. Sufficient oil ensures the stability of the output oil volume. At the same time, the flow rate can be adjusted by changing the position of the wedge-shaped throttle block 28.
